[vtkusers] vtkTreshold - Unit and Range? Adaptive?

[Ronald Römer]

Hello,

im interested in using a vtkThreshold on a set of DICOM images. My
problem is the follow:

1. Whats is the unit of the threshold and what is its range? (maybe
16bit pixels cause a range of 0-2^16)
2. I want a adaptive threshold to get an automatic threshold, where
can I do this?

Thanks
